Quarks and spinning tops

The classification of baryon and meson states provided by the «quark» model is compared with that offered by the «spinning-top» model, in which the spin is the sum of three vectors the lengths of which determine the strangeness, isospin, baryon parity and mesonG-parity. for the lower lying baryon states and many of the meson states the two models are similar, being in fact identical for a baryon decimet and for the I− octet. Classification of all strongly interacting states known at present is shown to be possible without being led to expect the existence of quarks. The models differ, however, with respect to the states which they predict, an, Ω ofJ=1/2,I=0 being impossible to form in the spinning top model, whereas states with higher values of isospin appear without modifying this model in any way.
